Question

q =

The term q represents the heat energy that is gained or lost. Cp
is the specific heat of water, m isthe mass of water, and ΔT is the
temperature change of the reaction mixture. The specific heatand
mass of water are used because water will either gain or lose heat
energy in a reaction thatoccurs in aqueous solution. Furthermore,
according to a principle known as Hess’s law, theenthalpy changes
of a series of reactions can be combined to calculate the enthalpy
change of areaction that is the sum of the components of the
series.

In this experiment, you will Use Hess’s law to determine the
enthalpy change of the reaction between aqueousammonia and aqueous
hydrochloric acid. Compare your calculated enthalpy change with the
experimental results.

You will conduct the following three reactions in this
experiment. In the space provided below, write the balanced net
ionic reaction equations from the descriptions. Use the table of
thermodynamic data in your text (or another approved resource) to
calculate the molar enthalpy of the reactions.Reaction
